I have this one linked below you can set the turn on and shut off temperatures so what I'll do in the summer is I'll swap them and I'll say turn on the power for my fans when it gets above 70° and turn it off when it gets below 69°. Right now I can set both on and off so I set on for 32 degrees and off for 33 degreesAKA Thermo Cube. We have the name-brand ones and some less expensive ones, too, we recently bought. The only thing I have against these later-purchased ones is that they shut off at 50°F, and the Thermo Cube ones shut off at 45°F. Not a big deal for just one of them, but we've got several.

That may help solve your shut off problem if you ever decide to get more of them
